HYDRAULIC RIVETING TOOL.

SPECIFICATION forming part of Letters Patent No. 641,162, dated January9, 1900.

Serial No.'71'7,439x N0 model.

T0 to whom it may concern:

Be it known that I, FRANCIS I-I. STILLMAN, a citizen of the UnitedStates, residing in the city of New York, borough of Brooklyn, in thecounty of Kings and State of New York, have invented a certain new anduseful Improvement in Hydraulic Riveting-Tools, of which the followingis a full, clear, and exact description, reference being made to theaccompanying drawings, forming part of this specification.

This invention relates to improvements in hydraulic riveting-tools bywhich the railbonds of electric railways are riveted to the rails; andthe object of the invention is to provide a tool by which thebond-rivets may be properly upset in holes punched in the flanges ofgirder-rails and the bases of T- rails and girder-rails, aft-er, as wellas before, the rails have been permanently laid.

On the accompanying sheets of drawings,

Figure l is a front elevation of the tool made for riveting bonds to theflanges of girderrails; Fig. 2, a side and sectional elevation thereofand cross-section of a fragment of a rail, the tool being shown on therail as it is placed when about to be used. Fig. 3 is a side elevationof the tool made for riveting bonds to the bases of T-rails orgirder-rails and a cross-section of a T-rail and shows the tool attachedto the rail as when'it is in use, and Fig. 4 is a plan of a guide-barand part of a clamp. 7

Similar reference-numerals designate like parts in different views.

This riveting-tool is used to upset the rivets of the rail-bonds inholes made in the flanges of girder-rails and the bases of T- rails orgirder -rails by certain punchingtools, which are described in otherapplications for patents, the rails being bonded by means of these toolsmore conveniently, effectively, and durably than by the common practice,in which the bonds are secured to the webs of the rails.

The body of this tool resembles that of a common hydraulic riveter, itbeing composed, when the tool is made for riveting bonds to the flangesof girder-rails, of the short U- shaped frame 1, whose lower branchforms fixed jaw 10, and of the cylinder 11 on the upper branch of theframe 1, the entire body being a single steel casting. In the jaw 10 isa block or anvil 12, and in the cylinder 11 is a ram, in which is fixedthe rivet-set 13,which has a convex peen. The ram-cylinder 11 has on ittwo pairs of ears let, one pair being near the top and the other nearthe lower end of the cylinder. The head 2 is mounted on the cylinder 11,its lower end being screwed into the top of the cylinder. The headcontains the pump by which the rain is actuated. and with which thepump-handle is connected at the back of the head, and on the top of thehead is a post 21, in which is fixed a screw 22. A bar 3, of which afront view, cross-section, and plan are shown in Figs. 1, 2, and 4,respectively, is fastened under the cylinder 11, on the lower ends ofrods 30, which extend through the ears 14 on the cylinder and on theupper ends of which is a yoke 31, the ears 14: forming guides and therods being adapted to slide therein. These rods are screwed into holes32 in the bar 3. The axes of the holes 32 are in the plane which alsocontains the axis of the rivet-set and are equally distant from theother axis or its prolongation. The screw 22 passes through the yoke 31,and

on the screw, above the yoke, is a nut 23,

which is provided with a handle 24. The central part 33 of the bar 3 isclose to the frame 1, as appears by Fig. 2, and on the under side ofthis part of the bar, at its ends, are projections 34c. The front facesof these projections are in a plane which is parallel to the planecontaining the axes of the holes 32 and which is at the same distancefrom that plane as the axes of the holes which are punched in the railsto receive the bond-rivets are from the edges of the flanges of therails. The other parts 35 of the bar 3, which extend in front of andbeyond the ends of and a little below the part 33, are flat on thebottom, their under surfaces being in one plane, and in their ends aresemicircular notches 36, whose curvature corresponds to that of thestems of the bond-rivets. The axes of curvature of these notches are inthe plane which also contains the axis of the rivet-set, and thedistance of each of them from that axis or its prolongation is the sameas the distance between the axes of the rivets of the bond. Handles 37,

by which the tool may be lifted and carried, are secured to the rods 30.The ram is raised by the common means of a rack and pinion in theram-cylinder and the lever 15, by which the pinion is actuated.

The holes made in the flanges of the rails byone of the punching-toolsabove mentioned are tapering, being smaller at the bottom, where theyconform closely to the stems of the bond-rivets, than they are at thetop. The bond with which two abutting rails are to be bonded is heldproperly under the flanges of the rails, and the rivets of the bond arepushed up through the holes until the heads of the rivets are in contactwith the flanges, when the stems project a little above the flanges. Theriveting-tool is set on the rails so that the bar 3 rests on the flangesof the rails with the projection 34: in contact with the edges of theflanges and with one end of the bar in contact with the stem of one ofthe rivets in one of the notches 36, the bar being on that side of thestem which is toward the abutting ends of the rails. Then, as will beseen from the foregoing description, the axis of the rivet-set coincideswith the prolonged axis of the other bond-rivet and the anvil 12 isdirectly under the head of the latter rivet. The bar 3 thus serves as aguide which facilitates the proper adjustment of the tool on the rails.Then the nut 23 is turned by the handle 24 against the yoke 31, and thehead and body of the tool are drawn upward until the head of the rivetwhich is to be upset is clamped against the flange of the rail by thejaw 10 and the bar 3, the head of the rivet be ing on the anvil 12. Bythis means, too, the tool itself is clamped to the rails. It isimportant that the heads of the rivets should be firmly held against theflanges of the rails during the riveting operation, since if they werenot so held probably the heads of the upset rivets would not touch theflanges, whereas to insure a permanent proper contact between the rivetsand rails the flanges of the rails ought to be squeezed hard by theheads of the rivets and the upset stems. The ram is actuated by pumpingwater from the head into the ram-cylinder. When the rivet-set acts on arivet, it both crushes and spreads the stem, forcing the upset part ofthe rivet to conform to the shape of the hole from end to end, and itdepresses the top of the stem a little below the top of the flange ofthe rail. The rivets of a bond being thus upset in the abutting rails,the attachment of the bond to the rails is secure and a superior contactis established between each of the rivets and the corresponding rail,the surfaces of contact being more than commonly large and the contactbeing very tight throughout the whole extent of those surfaces.Moreover, the rivets are so protected by the flanges of the rails thatit is not likely any rivet will be subjected to pressure or a blow hardenough to loosen it.

lVhen the tool is made for riveting bonds to the bases of T-rails orgirder-rails, its form is a modification of that shown in Figs. 1 and 2,different forms of tools being required in consequence of the differencein the forms of the rails. In this modification the body of the tool,the rivet-set, and the rods on the sides of the ram-cylinder are longer,respectively, than the corresponding parts in the other form, and thetool is provided with a hook 16, as appears by Fig. 3, which engages thehead of the rail and helps to keep the tool in its proper position whenit is to be clamped to the rail; but the modification produced bylengthening these parts and adding the hook 16 is substantiallyeverything that distinguishes one form of the tool from the other. Adescription in detail of the construction and operation of the tool madeas it is shown in Fig. 3 would be almost a repetition of the foregoingdescription, and it is not believed to be necessary to enable themodification to be fully understood. As each of the parts shown in Fig.3 is designated by the number of the corresponding part shown in Figs. 1and 2, a comparison of each form of the tool with the other can be madeand the differences between them ascertained without difficulty.

It is to be observed that whether the rails bonded by this riveting-tooland the punching-tools above mentioned are girder-rails or T-rails allparts of the bonds except the stems of the rivets are underneath theflanges or bases of the rails, where they do not interfere with thefish-plates or other rail-fastenings and where they are practically safefrom injury.
